net-Shield
An Easy and Simple Anti-DDoS solution for VPS,Dedicated Servers and IoT devices based on iptables
An Easy and Simple Anti-DDoS solution for VPS,Dedicated Servers and IoT devices based on iptables.
Requirements
Linux System with python, iptables
Nginx (Will be installed automatically by install.sh)
Quickstart
Running as a standalone software (No install.sh required) via DryRun option (-dry) to only check connections agains ip/netsets and do not touch iptables firewall.
python nshield-main.py -dry
For complete install:
cd /home/ && git clone https://github.com/fnzv/net-Shield.git && bash net-Shield/install.sh
WARNING: This script will replace all your iptables rules and installs Nginx so take that into account
Proxy Domains
To configure proxydomains you need to enable the option on /etc/nshield/nshield.con (nshield_proxy: 1) and be sure that the proxydomain list (/etc/nshield/proxydomain ) is following this format:
mysite.com 123.123.123.123
example.com 111.111.111.111
Usage
The above quickstart/installation script will install python if not present and download all the repo with the example config files, after that will be executed a bash script to setup some settings and a cron that will run every 30 minutes to check connections against common ipsets. You can find example config files under examples folder.
HTTPS Manually verification is executed with this command under the repository directory:
python nshield-main.py -ssl
The python script after reading the config will prompt you to insert an email address (For Let's Encrypt) and change your domain DNS to the nShield server for SSL DNS Challenge confirmation. Example:
I Will generate SSL certs for sami.pw with Let's Encrypt DNS challenge
Insert your email address? (Used for cert Expiration and Let's Encrypt TOS agreement
samiii@protonmail.com
Saving debug log to /var/log/letsencrypt/letsencrypt.log
Renewing an existing certificate
Performing the following challenges:
dns-01 challenge for sami.pw
-------------------------------------------------------------------------------
Please deploy a DNS TXT record under the name
_acme-challenge.sami.pw with the following value:
wFyeYk4yl-BERO6pKnMUA5EqwawUri5XnlD2-xjOAUk
Once this is deployed,
-------------------------------------------------------------------------------
Press Enter to Continue
Waiting for verification...
Cleaning up challenges
Now your domain is verified and a SSL cert is issued to Nginx configuration and you can change your A record to this server.
How it works
Basically this python script is set by default to run every 30 minutes and check the config file to execute these operations:
Get latest Bot,Spammers,Bad IP/Net reputation lists and blocks if those Bad guys are attacking your server (Thank you FireHol http://iplists.firehol.org/ )
Enables basic Anti-DDoS methods to deny unwanted/malicious traffic
Rate limits when under attack
Allows HTTP(S) Proxying to protect your site with an external proxy/server (You need to manually run SSL Verification first time)

La intrebarea "de ce da Google vps gratuit?" raspunsul e: are bani de la Apple
=========================
Alphabet's Google has quietly scored a major coup in its campaign to become an enterprise cloud computing powerhouse, landing Apple as a customer for the Google Cloud Platform, multiple sources with knowledge of the matter told CRN this week. Since inking the Google deal late last year, Apple has also significantly reduced its reliance on Amazon Web Services, whose infrastructure it uses to run parts of iCloud and other services, said the sources, who all requested anonymity to protect their relationships with the vendors. Apple has not abandoned AWS entirely and remains a customer, the sources said.

According to the sources, Google executives have told partners that Apple is spending between $400 million and $600 million on Google Cloud Platform, although this couldn’t be independently confirmed. Also unclear is whether this range refers to an annual spending rate or a set amount of capacity. AWS said Apple's move to work with Google does not signify "competitive defection."
“It’s kind of a puzzler to us because vendors who understand doing business with enterprises respect [non-disclosure agreements] with their customers and don’t imply competitive defection where it doesn’t exist," said the AWS spokeswoman in an emailed statement sent to CRN late Wednesday. Spokespeople from Google and Apple weren’t immediately available for comment. Morgan Stanley, in a report released last month, estimated that Apple spends around $1 billion annually on AWS, but speculated that Apple may look to reduce that figure by moving more computing to its own data centers.
Cupertino, Calif.-based Apple is spending $3.9 billion to build new data centers in Arizona, Ireland and Denmark, the first of which is set to open later this year.
While it might seem odd for Apple to give business to a cloud service run by a bitter rival in the mobile device market, such arrangements aren’t uncommon in a public cloud market that’s seeing intense pricing pressure, particularly in compute and storage services. Reports of Apple using AWS and Microsoft Azure to run parts of its cloud services date back to 2011, although neither AWS nor Microsoft has ever confirmed that Apple is a customer.
But in an Apple iOS Security white paper published in 2014, Apple acknowledged that encrypted portions of some iOS files are stored in Amazon S3 and Microsoft Azure. Mountain View, Calif.-based Google, which last November hired VMware co-founder and former CEO Diane Greene to lead its cloud business, is said to be aggressively forming partnerships and swinging deals to bring in large enterprise customers. Last month, Google signed up Spotify, which runs part of its streaming music service on AWS, as a cloud customer. CRN reported last month that Google and Verizon were in talks about a strategic partnership involving a Verizon-branded hybrid cloud service running on Google Cloud Platform.
Although Google doesn’t break out cloud revenue, signing up Apple -- no matter what the size of the deal -- would give a huge boost to a vendor widely perceived as the distant No. 3 player behind AWS and Microsoft Azure in the public cloud. In the fourth quarter of last year, Google sales for only its Infrastructure-as-a-Service and Platform-as-a-Service products -- Compute Engine and App Engine -- came in under $300 million, according to an estimate from Synergy Research.
That's seven times less than the respective business for AWS, John Dinsdale, Synergy's chief analyst, told CRN.
Google entered the cloud market with a vow to undercut Seattle-based AWS on pricing, and industry watchers said Apple could gain pricing leverage with AWS and Microsoft by virtue of its Google cloud deal. Google's extensive fiber network linking its data centers is said to be a major competitive advantage when it comes to networking bandwidth costs. Cheaper networking would present significant savings for Apple data services like iCloud, iTunes and App Store, which must either push content to customers or shuttle massive amounts of backup data to the provider. "Google is laying a lot more fiber in a lot more areas, so they have a lot more reach [than other cloud players]," Michael Fraser, CEO of InfiniteOps, a cloud vendor that works with Google and other public cloud vendors, told CRN.
Although Fraser said he doesn’t have direct knowledge of Apple's deal with Google, he believes that Google is getting better at winning enterprise customers because it offers superior performance and pricing. "Google is actually the cheapest play in the market when you take into consideration everything they're doing and when you take into account their various incentives," Fraser said. "[They offer the] most cost savings, lowest pricing for what you actually get."
Fraser said Google Cloud Platform, according to his company’s internal testing, has "better performance than any of the other major cloud providers." While AWS is the cloud of choice for many startups that can't afford or don't want to build their own infrastructure, it also has a growing list of big-name enterprise customers. Google has seen a slower march of customers to its cloud, a list that includes Snapchat, PricewaterhouseCoopers, General Mills, Coca-Cola, HTC and Best Buy.
AWS has such a huge lead in the public cloud space -- with a 31 percent share of the market in the fourth quarter compared with Google's 4 percent, according to Synergy -- that losing some of Apple’s business likely won’t leave a lasting impact. Market researcher Gartner said last May that AWS has more cloud capacity in use than its next 14 competitors combined.
